Integration Patterns of International Communities in Cities
Power of Integration. Three groups of cities show similar
behaviour in the number of languages detected, in their
level of integration and in their relative ranges (A), as
shown in the normalized decay of their respective sorted
values of entropy (B). The Integration Skyline diagram (C)
let comprehend the distribution of each community in
function of the number of resident users detected in each
city and their respective entropy (i.e the color of the bars in
descending order). It may occur that small communities (in
terms of users) show higher level of integration than others
represented by higher number of detected residents. A
schematic spatial distribution of people is highlighted,
related to the three languages (D), plotted over a radius of
30 km measured from the barycenter of the city.

Benefits of mapping geolocalized data
• Maps are a mean of recording and storing information. All data that is relative to a certain place can be stored in maps and tables
• Maps unveil spatial patterns.
• Maps are an effective in presenting information and communicating findings

Workflow for the analysis of geolocalized data
• Define the question
• Look for data
• Select the methods and tools
• Perform the analysis
• Examine and improve the outcomes
• Share the outcomes
